| neuroblast | <embryology> Cells arising by division of precursor cells in neural ectoderm (neurectoderm) that subsequently differentiate to become neurons. (16 Dec 1997) |

| neuroblastoma | <oncology, tumour> Malignant tumour derived from primitive ganglion cells. Mainly a tumour of childhood. Commonest sites are adrenal medulla and retroperitoneal tissue. The cells may partially differentiate into cells having the appearance of immature neurons. The tumour shows a consistent deletion of the 1p36 region which is considered the site of the neuroblastoma I gene. Loss of the 1p36 region also correlates with amplification for the N-myc oncogene, particularly in later stages of the disease. Amplification of N-myc with DNA triploidy is associated with poor survival. Hereditary forms of the condition are rare and in such patients there is no risk for other cancers, which suggests a specificity of the antioncogene for neural tissues. (16 Dec 1997) |
